摘要： A solid state light apparatus with a solar shielded heatsink ideally suited for traffic controls. The current state of the art solid state traffic signals utilize LED arrays encased in the existing plastic or metal traffic signal cases which were originally design for incandescent bulbs. Unlike LED's, incandescent bulbs are insensitive to high temperatures. As a result heat will build up on the LED die because of the limitations of the existing incandescent case design. The apparatus mounts the LED array directly to a louvered external heatsink in contact with the air outside of the traffic signal case facilitating the dissipation of heat generated from the LED die and from the sunlight shining on the case. For 25% of all signals (those facing west), during the late afternoon sunset the lensing system will focused the sunlight directly on the LED die raising the die temperature an additional 20 C. The louvered external heatsink dissipates this form of heat as well allowing the LED die to remain much cooler.
摘要翻译：一种具有太阳能屏蔽散热器的固态灯装置，非常适用于交通控制。目前现有的固态交通信号灯采用最初设计用于白炽灯泡的现有塑料或金属交通信号灯箱中的LED阵列。与LED不同，白炽灯泡对高温不敏感。因此，由于现有白炽灯箱设计的局限性，LED将会在LED芯片上产生热量。该装置将LED阵列直接安装到与交通信号灯外部的空气接触的百叶窗外部散热器，从而有助于散发由LED管芯产生的热量和照射在外壳上的阳光。对于所有信号（面向西部的信号）的25％，在下午的日落时间，透镜系统将将阳光直接聚焦在LED模具上，将模具温度提高20℃。百叶窗外部散热器消散这种形式的热量，并允许 LED芯片保持较冷。

摘要： A solid state light apparatus suited for use in traffic control signals and having a unitary transparent cover generating a homogenous light beam. A solid state light source comprises an area array of LEDs uniformly illuminating a light diffuser to achieve the homogenous light beam. The unitary cover has a lens defined at an inner portion thereof, and an outer portion encompassing the lens adapted to sealingly secure to the apparatus housing. The lens is continuous with the outer portion such that water and other environmental elements can not penetrate into the housing electronics.

摘要： A modular solid state light apparatus ideally suited for use in traffic control signals. Current state of the art solid state signals are sealed units which fit into existing signal cases once the primary lens and incandescent bulb, and sometimes even the incandescent reflector, are removed. The modular system replaces the entire case with a custom case designed to accommodate current and future features at approximately {fraction (1/10)} the present cost of a stand alone system. These upgrade features include but are not limited to vehicle preemption, electronically steerable beam, predictive failure analysis, various power supplies, LED arrays in various colors, optical alignment tools used for installation, video camera, in car Telematics, video loop detection, red light running, various communications links, infrared sensors to sense people and vehicles under fog, rain smoke, and other adverse visual conditions, chemical ‘sniffers’, automobile emission monitoring, and adaptive control. The modular traffic functions are adapted to be selectively added and upgraded over the life of the signal, and permitting easy service thereof.
